T 0 all whom t may concern.'

Be it known that l, JOHN H. LEHMAN, a citizen of the United States, residing in the city of Elkhart, county of Elkhart, indiana, have invented certain new and useful limprovements in Traffic-Indicators, of which the following is a specification.

This invention relates to traffic indicators, and more especially to illuminated indicators of the character mentioned and de4 scribed, and adapted to be placed at street intersections.

An object of my invention is the production of an illuminated traiiic indicator for the center of street intersections. which is simple, effective, cheap and 'easily installed. Another object is the production of a 4traffic indicator of the character scribed in which improved drainage means is provided. A thirdA object is the production of a trahfic indicator having improved facilities for inserting or removing the lamps thereof. Other objects of my 1nvention arementioned and described herein.

rlhe preferred embodiment of my invention is illustrated in the accompanying drawin which Figure 1 illustrates my invention when placed at the center of a street'y ing intersection; Fig. 2 isa vertical section through the indicator device as a whole; and Fig. 3 is an exterior view in end elevation.

Similar numerals of reference indicate like members throughout the several views on the drawing.

the drawing in detail the numeral 1 indicates a base plate, preferably of cast metal, adapted t0 be embedded in the street in concrete or cement, and provided with the substantially funnel-form central structure 2 in which the opening 3 is formed and adapted to drain any moisture accumu- Referring to lation from the upper surface of said plate.

rlhe under side of the base plate 1 may be provided with a plurality of downwardly extending and radially arranged ribs t, i which may entend from the funnel mouth 3 outward toward the outer periphery of the base plate and which are adapted to be em bedded in the cement or concrete in which the plate is laid to edect a rigid and permanent connection between the plate and concrete.

The, numeral 5 illustrates the indicator body member which is preferably domed and somewhat 'oval in general configuration and which may be secured to the base plate 1 by bolts 6, 6.` The member 5 may be provided ywith a plurality of openings?, 7 in which glass plates 8,v 8 are rigidly mounted 1n any suitable mannerv and preferably. depressed below the outer face of the body member 5 to avoid breakage of vsaid plates by vehicle wheels. 4The member 5 may be provided with a hand Vhole 9' in its top medial portion which opening is adapted lto be closed normally by'afdanged cover 10 rel movably fastenedA in or over said opening by suitable screwsI 11', ll,`V said hand holecover being provided"withv the lateral flange 12 which. engages in the lateral recess 13 sur` rounding the opening 9 whereby the .outer periphery or face of said plate l() is brought substantially flush 'with the outer face of the member 5.

The cover 10 may be centrally apertured at 14 in which aperture the glassplate 15 maybe rigidly secured and depressed simi-. lar to the plates 8, Sand for the same purpose. rEhe interior of the indicator may `carry a plurality of incandescent lamps 16 and 17 supported upon a socketmember 18 which may be removably mounted upon a prong 19 vof the carrier member 20 rwhich may be rigidly secured to the base plate 1 by Screws 21, 21.

A conduit wire 22 may connect the lamps 16 and 17 with any suitable source of electric current. The carrier 2O is preferably made of bar metal to permit of the flow of water to the opening 3 which preferably communicates with the earth direct to enable the ready absorption of any such moisture which may accumulate within the indicator. When the lamps 16 and 17 are worn out vor damaged in any manner ready access thereto is gained by the removal of the hand-hole cover 10, and the lamp socket 18 may be withdrawn to the exterior of the cover 5 to install new lamps therein, whereby the necessity for the removal ofl the domed cover 5 is eliminated and lamp replenishment much simplified.

1. lin a traficindicator, a hollow body' member provided with a domed top portion, said domed top being provided with lUO adapted to serve as a handhole, said opening being relatively smaller than said domed top, said body *being provided. also with an` opening in its bottom Wall adapted vfor -mer to the latter; and a light mounted Within said bod member.

2. A tra e indicator comprising a base plate of substantially funnel-form structure, the bottom whereof is provided with a plurality of projections adapted to be embedded vided With 'a plurality of Windows; and an 15 electric light mounted beneath saiddomed cover.

In testimony whereof I have hereunto aixed my signature this 178th day of December, 1919. y
